摘要： The present teachings provide a device and methods of making and use thereof. Specifically, one aspect of the present teachings provides a device for restricting blood flow entering the lung after each right bean systole. Certain embodiments of the present teachings provide a device that prevents a complete closure of the pulmonary valve leaflets so that a certain amount of blood is allowed to flow from the pulmonary artery to the right ventricle at the end of a right ventricle systole. Other embodiments of the present teachings provide a device that restricts the amount of blood outflowing from the right ventricle to the pulmonary artery. In addition, the present teachings also provide a delivery system for implanting such a device approximately to or at the pulmonary valve.

摘要： Devices and methods to enhance the implantation, retreivability, or repositionability are provided. Embodiments of devices include pivotable sections providing the ability to maintain the device's engagement with a delivery system during implantation where the deliver system approaches an opening of the septum at an angle. Embodiments of devices also include configurations that allow for improved retrieval into a delivery system in the event that a malfunction or a problem with the patients physiology is detected.
